Hello,
I have upgraded my iPhone 3GS to iOS 4.3.1 by mistake. My baseband is 5.16.02. I want to jailbreak it and unlock it. If i have understood correctly, I will need to upgrade my baseband to 6.15 in order to unlock the phone. I'm trying it with redsn0w(redsn0w_0.9.6rc12) on Windows 7, however a strange error is occurring. When it goes to step "Fetching iPad baseband files (please be patient)", after 1 minute or so, the redsn0w exits automatically without giving any error. The phone remains in the DFU mode, I have tried this so many times but it always does same. I have tried to run the redsn0w in XP compatibility wity administrator permissions, also I have tried on another PC.
Can someone please help me with this error. How can I fix it. Thanks a lot.
